The hollow spindle e ofthe'dampero passes through the stovepipem. The upper portion of the spindle e hasa' slota. formed there'- k in, which when open permits thefa'dmission of'airnecessary to s'low'c'o mbustion', as shown in Fig. 3. A metallic'plate g is provided for the purpose of clo'sing'the slotct', thus allowing no air to be admitted into pipe m. The

hollow spindle e has a slot inits lower portion, f through which the air enters into; the said. spindle, up through the same, and out atthe 'In the lower end tom of the stove and carries atoothed sections and an arm 15 in order to operate the door k of eral movement on its pivot. Thus when the door is operated to move laterally; the steps at, when door k 'bears' against the projection-t of the stove, permit a certain amount of air to enter, according to thedistance the door has moved. The toothed sector s and the toothed rack 2, arranged on the door,are used to efiect this lateral movement. 7 The arm t, i
